## Discrepancy

DURING PREFLIGHT, CREW NOTICED SEVERAL EMERGENCY LIGHTS WERE INOPERATIVE.  UNDER THE DIRECTION OF MX CONTROL THE CREW PLACED THE EMERGENCY LIGHT SWITCH IN THE COCKPIT IN THE ARM POSITION AND ALLOWED THE BATTERIES TO CHARGE.  AFTER THE SYS WAS CHARGED, AN OPS CHECK PRODUCED SATISFACTORY RESULTS AND THE AIRCRAFT WAS RELEASE FOR FLIGHT.
